WebRegulatory proteins often bind to small molecules, which can make the protein active or inactive by changing its ability to bind DNA. Some operons are inducible, meaning that they can be turned on by the presence of a particular small molecule. Others are repressible, meaning that they are on by default but can be turned off by a small molecule.
